'73 Claims.

This invention relates to machines for applying rcinforcingmaterial to insoles such as are used in the making of weltedshoes, and particularly to machines for applying a strip of fabric such as duck or canvas to the inner face of the rib and to the insole adjacent to the rib.

In'the manufacture of welted shoes it is customary to employ a leather insole provided with an inside and an outside channel, the lips of the channels being turned up and secured to each other to form a rib, th insole thus formed being usually reinforced by a layer of fabric such as Gem duck applied to the entire surface of the insole inside the rib and to the inner face of the rib, the fabric being trimmed flush with the top inforcement of the interior portion of the insole is unnecessary since, if such reinforcement is '1 omitted, no appreciable lateral stretching of the portion of the insole between the ribs, due to lasting or other strains during the manufacture of the shoe, is found to occur and, during the wear of the shoe, the lateral stretching is found to be negligible whether or not the insole has an all-over reinforcement. The chief function of the reinforcement is, therefore, to reinforce the inseam and the inside channel, for which a strip economy of reinforcing material, a double reinforcement of the insole at the toe is provided,

the reinforcing operation may be performed veryquickly and uniformly, and whereby trimming of reinforcing material extending beyond the top of the lip is obviated.

The illustrated machine comprises mechanism ,5

for supporting and feeding an insole past an operating point where an applyingroll presses one marginal portion of a reinforcing strip against the body of the insole adjacent tothe rib while the other marginal portion of the strip is first bent toward the direction from which the work is being fed and is then turned into a position extending lengthwise of the inner face of the rib and parallel thereto, means being provided for pressing this marginal portion against the inner face of the rib. I

It is to be understood that the strip and the portion of the insole to which it'is to be applied have both been previously coated with pressureresponsive cement so that instant adhesion of the strip to the insole is effected as soon as the two are pressed together.

In order to provide a double reinforcement for the rib at the too, a portion of the strip is first applied along one edge of the insole and then another portion of the strip is applied along the other edge of the insole, the ends of the strips overlapping each other at the toe end of the 'insole. In order that the same machine may be used for applying both portions of the strip, one strip is laid from the toe end of the insole toward the breast line and the other strip is laid from the breast line toward the toe of'the insole.

In laying a portion of the strip against the body of the insole along the curves of the rib which occur particularly at the ball portion of the insole, it is necessary that the strip shall not move laterally with respect to the applying roll and that the length of different longitudinally extending parallel portions of the strip shall correspond to the length of the portions of the insole against which they are laid. That is, suppose a portion of the strip is being laid against the insole along the base of a portion of the rib insole located inwardly thereof with respect to the rib,. then the portion of the strip laid next to the rib should be shorter than the portion'laid at a distance from the rib. Accordingly, the applying roll is so constructed as to control these portions of the strip so that their lengths will substantially correspond to the lengths measured on the insole against which they are laid. This is effected, as illustrated, by dividing the applying roll into separate, freely rotatable sections or disks, one disk engaging the strip near the base of the rib, another disk engaging the part of the strip remote from the rib, and an intermediate disk engaging the strip between the inner and outer portions. Each disk is provided with sharp points or spurs long enough to hold the portion of the strip engaging the disk against substantial movement relatively to that disk. The resulting control of the strip is so accurate that the width of the marginal portion laid against the body of the insole does not vary substantially and consequently the marginal portion laid against the rib of the insole is substantially constant and no trimming of portions thereof which extend above the top of the rib is necessary.

A continuous feeding movement is imparted to the insole by positively driven upper and lower feed rolls which engage the feather portion ofthe insole, bend it somewhat toward the inner face .of the insole and support the rib in an upright position.

The applying roll moves from an inoperative position above and to the left of the feed rolls to an operative position where its axis is substantially coincident with that of the upper feed roll.

which is convex with relation to a point on the To insure that the end of the strip will properly engage the applying roll as it moves into operative position, a finger is provided which is brought against the strip during movement of the applying roll toward the operating point and insures that the strip will properly engage the spurs on the applying roll.

To assist the operator in guiding the work to the feed rolls and applying roll, two guides are provided, one for engaging the inner face of the rib and the other its outer face, both guides being arranged close to the operating point. These guides steer the rib to the feed rolls and applying roll to enable the machine to be operated with less attention on the part of the operator. The guide engaging the inner face of the rib is released automatically by engagement of a finger with the rib at the toe of the insole.

Adjacent to the operating point is a guard against which the insole is raised after the strip has been applied to one side thereof. A pair of pivoted shear blades is arranged to move from an inoperative position into an operative position just above the guard. Means under the control of the operator is provided to move the shears into operative position and to close the shears to sever the strip, the arrangement being such that the closing movement cannot occur until the movement into operative position has been completed. To prevent interference between the applying roll and the shears, means is provided to prevent operation of the shears unless the applying roll has moved out of their path.

When starting at the toe end of the insole to apply the strip, it is desirable that the free end of the strip extend considerably beyond the applying roll and, when starting at the breast line to apply the strip, a free endof less extent is desired. Accordingly, means is provided for moving the applying roll alternately to different distances from the cutting point so that long and short free ends of the strip will be provided as required for the strip-applying operation as described.

When the applying roll is operated to bring the longer free end of the strip into contact with the insole at the toe, the strip is apt to engage the guard and be turned up away from the insole. Means is therefore provided for insuring that this upturned end be smoothed down into contact with the insole so that the end of the second strip, when it is laid, will lie over the end of the first strip.

Since the strips overlap each other at the toe end, it is desirable that cement be applied between the overlapping portions of the strips to cause them to adhere. Accordingly, a cementapplying device is arranged automatically to apply a drop or two of cement to the toe end of the first strip before the toe end of the second strip is laid over it. When the laying operation is about to be finished at the toe, it is desirable to release the guide which engages the inner face of the insole to prevent its engagement with the rib of the insole. Conveniently, therefore, the cement-applying device is carried by the inside guide, and a feeler arranged to engage the rib at the toe end of the insole acts not only to release the guide and permit it to rise but also actuates the cement-applying device.

In some cases the strip is treated with a thermoplastic stifiening agent, as disclosed in application for Letters Patent of the United States Serial No. 291,939, filed August 25, 1939, in the name of Stanley M. Griswold. In order properly to handle a strip thus stiffened in the machine of the present invention, it is desirable to heat the strip to render it limp just prior to its reaching the applying roll, and also to heat the applying roll to prevent too sudden cooling of the strip. It is also desirable to heat the strip only while it is being applied, thus preventing overheating of a portion of the strip when the machine is at rest. Accordingly, electric heating elements are provided and the arrangement is such that when the machine is at rest the strip is removed from the heating elements and, when the applying roll is lowered to the operating point, relative mutualmovements of approach between the strip and the heating elements are effected to bring them into close relation and cause the strip to be heated. A separate heating element is arranged to heat the applying roll by conduction.

These and other features of the invention will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

This machine for applying a reinforcing strip to the inside of the lip and against the body portion of an insole comprises a ICOILlmIl I0 on the upright I4. The forward portion of ther feed roll 22 is cylindrical and the rear portion- 30 frusto-conical, the rear portion of the table 24 being bent downwardly to correspond to the inclination of the conical portion 30 (Fig. 11).

A- supply of strip material S of indefinite length for reinforcing insoles is wound upon a reel 90 rotatably mounted on a frame 02 (Fig. 11) secured to the uprights I4, I3. The strip material does not need to be bias cut and may therefore be prepared b stripping up webs of material such as Gem duck which have preferably been given, while in the web, one or two coats of pressure-responsive cement such as latex cement. From the reel 90 the strip S of reinforcing material is first passed over a flanged roll 94' upon which it is held by a pin or. screw 35 (Fig. l), the roll and screw constituting a guide mounted on an arm 06 secured at 90 to an arm I00 (Fi 1) which is secured at I02 to The shaft I8 extends rearwardly beyond the up- 3 '22 but tapers in the opposite direction; that is,

the conical portions of the two rolls are parallel at the bite of the rolls and are adapted to receive between them the feather portion of a welt insole K and to bend it down at an angle to the plane of the body of the insole, thus causing the rib which is usually inwardly inclined to assume an upright position against the end face of the feed roll 40. I'he roll 40 is arranged for a limited amount of movement toward and from the roll 22 and, upon depression of a treadle (Fig. 13), is moved yieldingly toward the roll 22 by mechanism to be described and at the same time power is applied to the rolls by a belt 52 engaging the pulley 34 on the shaft I0, the rolls 22, 40 being thus [continuously and positively driven by power to feed the work. The belt 52 (Fig. 13) runs over a pulley 54 loose on a shaft 56 and having a friction face 58 adapted to engageand be driven by a continuously rotating friction disk 60 fast on the shaft 50. 60 is driven through reducing gearing 02 by a belt 34 leading to the pulley of an electric motor 60. The motor clutch and reducing gear are -mounted on a shelf 68 secured to the column I0, below the base plate I2, supported at its rear gaging the hub of the pulley 54 and the other arm I6 of the lever being connected by a rod I8 to a forked member pivoted at 82 to the Depression of the treadle 50, therefore, moves the feed roll 40 into engagement with the work and presses The disk,

an arm I04 extending at right angles to a shaft I06 journaled in the uprights I4, I0. After being passed through the guide 04, the strip S passes through a guide I0! (Figs. 3 and 7) and then over a plate I08 against which it is pressed by a leaf spring III] pivoted -at- II2 to an arm H3 and having an adjusting screw II4 bearing upon the spring IIO between its ends and providing means for varying the pressure of the spring against the strip S and hence the tension of the portion of the strip which is being conducted to the point of application to the insole. The plate I08 is pivoted at II 6 to ears II8 securedat I20 to a bracket I22 carried by the arm I00 and is urged toward the roll I30 (Fig. 3) by a spring I23. The plate I08 (Fig. 7) carries a guide comprising a second plate I24 spaced from the plate I03 an amount slightly more than the thickness of the strip and adapted to accommodate its width. The rear part of the guide is bent to- Ward the right (Fig. 8), that is, toward the direction from which the insole is fed, about an .axis extending lengthwise of the strip so the rear marginal portion of the strip is held at an angle to the remainder of the strip (Fig. 3). The angle between the portions of the strip may be approximately a right angle but preferably is substantially more than that. The plate i0 3 extends downwardly beyond the guide I 24, its right-hand edge I26 (Fig. 7) being convexly curved with its lower end lying close to the surface of the insole K when the machine is in operation (Figs.'3 and 8).

After leaving the guide I 24, the strip S for the greater part of its width engages an applying roll, generally designated .bythe numeral I30, constructed as shown in Fig. 4. A stud I32 having a head I34 at one end and a reduced portion I35 at the other carries a series of three disks I38, I30 and I40, the reduced portion I33 being threaded through the lower end of the arm I00 and being further secured by a nut I42. The disks I38, I 39 and I40 rotate freely on the stud I32 and are provided about their periph- I eries with sharp-pointed spurs I44 which are sufficiently long to'pass through the fabric strip, though they need not be long enough to engage the insole became at the point of application they engage the tape after it isstuck to the insole. strip, effectively prevent any movement of the strip with respect to the applying roll except away from the roll in the direction of the spurs. The meeting faces of the disks I38, 530 and I40 may be provided, as shown in Fig. 6, with grooves I43 extending tangentially of the stud I32, the purpose of the grooves being to cause any cement which may accidentally get in between the disks The spurs I44, when engaged by the to work out along the grooves. The applying roll is adapted to apply a major portion of the. width of the strip to the body of the insole, including the inside channel from which the inner lip is raised, and accordingly the disk I40 of the applying roll has a portion of larger diameter than the other disks and the head I34 of the stud is made of a size to correspond with the diameter of the larger part of the disk I40. Moreover, the head I34, which, of course, does not rotate with the disks, is made thicker on its lower side so that the portion of its face presented to the rib is inclined away from the rib. Thus, the lower portion of the head I34 constitutes a lip I46 for tucking the marginal portion of the strip into the angle between the rib and the body of the insole, and, of course, rubs a portion of the strip adjacent to the rib against the body of the insole. The head I34 also serves to space the spurred disk I40 away from the rib and prevents the spurs from catching on the upturned portion of the strip or on the rib itself, which might result in displacing those parts. It will be seen also that the end of the upper feed roll 40 cooperates with the lip I46 to press the rib and the marginal portion of the strip together, the end face of the feed roll 40 and the head of a screw I41 which holds it on its shaft being slightly conical so that the portion which contacts with the outer face of the ribis parallel;

to the surface of the lip I46 which presses the strip against the inner face of the rib. Of course, if the rib is thicker at the bottom than at the top, the conicity of the feed roll 40 may be increased.

The action of the spurred disks I38, I39 and I40 which constitute the applying roll I30 is to meter the strip before it is pressed upon the insole. When the insole is traveling in a straight line perpendicular to the axis of the applying" roll, the disks, of course, all travel the same distance in the same time and the length of the widthwise portion of the strip laid by each disk is the same as the distance traversed at that time on the insole by the disk which engages that portion. The three spurred disks I38, I39 and M engage three longitudinally extending parallel portions of the part of the strip which is laid against the body of the insole. Each of these parallel portions may be regarded as under the control of the spurs on one of the disks. Since the spurs at the under side of the disks engage the strip where it is pressed against the cement on the insole and where it is thus rendered immovable with respect to the insole, each section of the roll, that is, each disk, is by its spurs geared to the strip and hence to the insole. Thus, when the strip is being laid along the base of a curved portion of the rib, it will still be true that the length of each of the three parallel portions of the part of the strip laid against the body of the insole will be equal to the distance traveled by the disk which engages that portion. For example, where the rib is convex with respect to a point inwardly of the rib the disk I40 will travel a shorter distance than the disk I38, and the disk I39 will travel an intermediate distance, the difference in the distances traveled by the disks depending of course upon the radius of the curve. The strip cannot slip lengthwise or sidewise when engaged by the spurs since the spurs prevent slippage of the disk with respect to the insole. The spurs on each disk will compel the length of the portion of the stripilaid by each disk to correspond up so that its edge will reach the top of the rib, no trimming of that edge being necessary.

1n order to present a marginal portion S (Fig. 5) of the strip S in a position parallel to the inner face of the rib, the portion S of the strip which is bent forward relatively to the wider portion S by the guide I24 is carried over the edge i26 (Fig. 3), assuming the shape indicated at I26 (Fig. 5) and then extends as at S parallel to the inner face of the rib against which it is rubbed by the lip I46 (Fig. 4). The remainder of the width of the strip S (Fig. 5) is, of course, forced by rolling pressure against the body portion of the insole and caused to adhere thereto, as illustrated in Fig. 4. The inoperative position of the strip guide and applying roll is shown in Figs. 2 and '7.

To move the parts from that position to the operative position shown in Figs. 1, 3 and 8 the following mechanism is provided: The shaft I06, on the arm I04 of which the applying roll I30 is carried, has secured thereto near its rear end a lever the left-hand arm I48 of which (Fig. 8) is connected to a rod I49 which is drawn down yieldingly by depression of the treadle 50.

To wrap the strip S around the applying roll i230 so that it will be presented properly to the insole and to cause the spurs to enter the strip, a finger I50 (best shown in Figs. 1, 2, 7 and 8) is provided. This finger is pivoted at I52 to the arm I04-between its ends and at its upper end has a tension spring I54 connected thereto and to a pin I56 upon the arm I04, the spring I54 acting to urge the finger I50 toward the applying roll I30. The finger I50 is held in inoperative position, as shown in Fig. '7, by engagement of a rearwardly directed flange I58 thereon with a fixed, forwardly directed lug I60 on a bracket I63 (Fig. 12) secured to the upright I4 and, as the arm I04 swings downwardly to move the applying roll I30 into operative position, the finger moves down relatively to the lug I60 which, as the swinging movement occurs, allows the spring I54 to swing the curved lower end of the finger I50 against the strip S and press it against the applying roll I30 before the roll reaches its operating point. The finger I50 engages the strip S substantially at the point where the largest diameter of the disk I40 begins (Fig. 4) and a stop pin I6I (Fig. '7) on the arm I04 arrests the finger before it actually contacts with the applying roll I30 if no strip is between it and the roll.

In order that the insole may be properly guided to the applying roll so that the strip will be applied to the insole from end to end thereof with little or no attention on the part of the operator, two rib guides are provided, one, I62 (Fig. 7), for engaging the outer face of the rib and the other, I64, for engaging the inner face. These guides are normally raised, as shown in Fig. 7, to facilitate insertion of the work and, by movement of the treadle 50, are lowered into positions respectively opposite the outer and inner faces of the rib (Fig. 8 To effect this (Fig. 8) a lever arm I66 opposite the lever arm I48 is connected to a rod I68 having a threaded lower portion passing through an ear I10 connected at I12 (Fig. 11) to the rear arm I14 of a lever fulcrumed at I16 and having a forward arm I18. The arm I18 is loosely pivoted to a bar I80 which, at its upper end, has adjustably connected to it a latch I8I (Fig. 11 which hooks over an arm I82 pivoted at I84 to a bracket I86 secured at I88 to the frame of the machine. The outer end of the arm I82 carries the guide I 64 which engages the inner side of the rib. The latch I8I is adjustably held to the bar I80 by a screw I83 passing through a slot in the latch I8I and threaded into the bar I80 which carries a pin I85 engaging an open slot in the latch I8I to prevent relative turning: of the parts I8I, I80. The bar I80 has a hole in its lower end through which a screw I81 loosely passes. Between thelink and the head of the screw I81 is a spring I89 which permits the latch I8I to swing out as the beveled upper end of the latch engagesthe arm I82.

The guide I62 which engages the outer face of the rib is formed by the front end of a lever pivoted at I90 (Fig. 11) to the bracket I88 and having a rear arm I92 provided with an adjustable stop screw I 94 which is in position to be engaged by the arm I14 at a point near its fulcrum so that, as the lever I14, I18 is rocked on its fulcrum I16 to lower the guide I64, the screw I94 is engaged by the arm I14 and moved upwardly to lower the guide Hi2 also into operative position.

The lever arm I18 is pivoted at I95 to a block I91 having a hole through which the shaft 38 passes and a downwardly open slot which straddles the shaft I8. Accordingly, as the lever I14, I18 is operated to move the guides I 62, I64 toward the work, the upper feed roll 40 is brought down into engagement with the feather of the insole.

As the shaft I is rotated counterclockwise (Fig. 1) by depression of the treadle 50, the arm I66 moves the rod I68 upwardly until nuts I96 engage the ear I (Fig. 8) and lift the lever arm I14 to operate the guides as described. A compression spring I98 is provided on the rod I08 between the ear I10 and nuts 200 on the rod the purpose of which is to raise the guides when the treadle is released.

The machine is intended for laying a reinforcing strip S first on one side of an insole from the toe end to the breast line (Fig. 14) and then laying another strip S from the breast line along the other side of the insole to the toe (Fig. the strip in each case extending slightly beyond the rib at the toe and the end of the second strip being carried across the end of the first strip so as to provide a double reinforcement at the end of the toe. The method practised is fully disclosed in the application above mentioned.

To facilitate this work the machine is provided with means for cutting a strip after a portion thereof has been applied to either side of the insole. This cutting mechanism, as shown in Figs. 2, 9. l0 and 13, comprises apair of shears which normally occupy an inoperative position (Fig. 9) and which are moved into operative position (Figs. 2 and 10) and-operated to sever the strip by a solenoid the operation of which is controlled by a switch adjacent to the operators kneef The shears (Figs. 9 and 10) comprise a blade 202 and a blade 204 pivoted shown in Fig. 10, the blade being thus carried from inoperative to operative position with reslide 208 in both directions.

spect to the strip S. The slide 208 reciprocates on a block 209 which is supported on two struts 2 (Fig. 12) fixed to the frame, there being a pin 2I3 (Fig. 9) in the slide 208 engaging a slot 2I5 in the block 209 to limit movement of the A second slide 2I0 is arranged on top of the slide 208, and is provided with slots 2I2 extending lengthwise of the slide through which pass headed screws 2I4 to secure the two slides 208 and 2"? together while permitting lengthwise relative movement thereof.

The blade 204 has a portion 2I6 extending beyond its pivot 206 which carries a screw 2I8, the screwpassing through an inclined'slot 220 in the slide 240.

right relatively to the slide 208 will cause the shear blades 202, 204 to close, as will be seen from Fig. 10 where they are in the act of closing. From this figure it will also be clear that the blades 202, 204 have their cutting edges so inclined to each other that as they close they begin to cut at the outer end and therefore out the strip beginning at its front edge and working toward its rear edge. This has been found advantageous since, when shears having blades cutting in the usual direction from the pivot toward the points were tried in the machine, they tended when closed to push the strip out from between the blades, whereas. with the arrangement shown the position of the strip is not disturbed and a clean cut across the strip is assured. Rearward movement of the slide 2I0 is limited by stop pins 22I set in the slide 208.

To operate the shears (Fig. 12) a bell-crank lever having an upright arm 222 and a horizontal arm 224 is pivoted at 226 to the machine frame. The arm 222 at its upper end is pivoted at 228 to the slide 2110 and-the horizontal arm 224 is pivoted at 230 to the armature 2320f a solenoid 234. Current for the solenoid is controlled by a push button switch 236 (Fig. 13) located behing a stiff but padded flap 238 pivoted at 240 to the column I0. By pushing the flap 238 toward the column with his knee, the operator can close the switch 236 to cause the solenoid 234 to be energized, the armature 232 being. then drawn downwardly and the bell crank 222, 2-24operated to move the slide 2I0 forwardly. This moves the shear blades 202,, 204 forwardly into operative position and causes them to close to sever the strip.

To insure that the blades will not close before they reach operative position, the following mechanism is provided: A plate 242 (Figs. 2, '7, 9 and 10) is pivoted near one edge to two ears 1 254 on a fixed support 245 (Fig. 2) and a leaf spring 248 secured to the support by screws 248 bears against a square edge on the plate 242, thus yieldingly holding it in horizontal position but permitting the edge opposite the pivot to be lifted. Along the edge of the plate 242 opposite its pivot is a downwardly projecting ledge 250 which is beveled on its outside lower portion (Fig. 2). The'screw 2l8 may also have its head beveled on the .side toward the pivot of the plate 242. During the movement of the shears from inoperative to operative position, the screw head 2I8 remains in engagement with the ledge 250 and the blades cannot close. When the blades have reached operative position (Figs. 2 and 10) the screw 2I3 has passed beyond the ledge 250 so that the shears will. close as described and when fully closed the screw Zldwill be outside of the ledge 2'50 where it may remain during the retracting movement of the shears.- When the slide 2I0 is Movement of the slide 2I0 to the nearly fully retracted by means of a spring 252 connected to the arm 222 at one end and at the other to a pin 254 upon the frame, the blades will be opened, forcing the head 2I8 under the ledge 259 to its initial position.

Should the solenoid 234 be energized to operate the shears when the applying roll I39 and its carrier are in operative position, that is, when the treadle 59 is depressed, the shears would contact with the roll carrier and be likely to damage the machine. To prevent this occurrence the mechanism shown in Fig. 13 is provided. The block 89 pivoted to the treadle lever 59 at 82 is provided with a rod 269 having a bifurcated upper end pivoted at 262 to a lever 264 fulcrumed at 296 on the column I9. A rod 268 is secured to an ear 219 on the lever 264 and has its bifurcated upper end pivoted at 212 to a stop lever 214 fulcrumed at 216-on an ear 218 secured to the shelf 99. When the treadle is depressed the stop lever 214 is rocked on its fulcrum 216 to cause its front end to assume a position between the column I9 and the flap 238 so that the flap cannot be pushed toward the column far enough to close the switch 236 which causes the solenoid 234 to be energized. Hence the shears can be operated only when the applying roll is raised far enough so that the shears can pass beneath it.

The lever 264 (Fig. 13) is also utilized as part of the mechanism for moving the applying roll I39 to operative position. A rearward extension 289 of the lever 264 is connected to a rod 282 which, at its upper end, is pivoted to a lever 284 (Fig. 12 between its ends. One end of the lever is fulcrumed at 289 to a bracket 288 secured to the head of the machine and the other end isprovided with a flattened portion 299 having a hole through which the rod I49 passes. Fixed on the rod 149 is a collar 292 having on its lower side a knife edge to engage the flattened portion 299 and slidingly mounted on the rod I49 below the portion 299 is a collar 294 having on its upper side a knife edge to engage the portion 299. Between the sliding collar 294 and nuts 296 on the lower end of the rod I49 is a long compression spring 298. Depression of the treadle pulls downwardly on the rod 282 and operates the lever 284 to pull downwardly yieldingly on the rod I49 which, through the spring 298, operates the lever arm I48 (Fig. 8) to turn the shaft I96 in a counterclockwise direction to lower the applying roll I39 into operative position (Fig. 13). To raise the treadle 59 a tension spring 299 (Fig. 13) is connected at its lower end to a collar on the rod 282 and at its upper end to a bracket 39I secured to the machine head (Fig. 12).

The shaft I99 is mounted for limited endwise movement and is urged rearwardly by a spring 399 mounted on the shaft I96 between the upright I4 and a collar 392 fixed to the shaft 193. Rearward movement of the shaft is controlled by a'roll 394 (Fig. 12) which engages a cam face 396 formed on a block 398 secured to the upright I 6. The roll 394 is carried by the lever arm I48 at a short distance from its axis I96 and, as the lever arm I48 is operated to bring the applying roll I39 into operative position, the roll 394 rides along the surface 396 and, when the applying roll has reached substantially its operative position and is about to contact with the insole, the roll 394 passes on to a drop 3I 9 on the cam face 396 which allows the shaft I96 to be forced rearwardly by the spring 399 and cause the lip I45 on the head I34 to be forced into the angle between the body of the insole and the inner face of the rib, thus pressing the upturned portion of the strip against the rib R of the insole which, of course, is supported on its outer face by the slightly conical end face of the feed roll 49 and of its screw I41. Turning movement of the shaft I93 to move the applying roll 239 into operative position is limited by a stop 3 secured to the lever arm I48 which, when no insole is in the machine, engages a face 3I3 formed on the upright I6 and prevents the spurred roll I39 from engaging the rubber-covered feed roll 22 should the treadle 59 be depressed.

The machine is provided, adjacent to the shears 292, 294, with a guard 3I2 (Figs. 2 and 7) which extends forwardly beyond the ends of the shear blades when they are in operative position and thus protects the operator from contact with them when they are operating. To support the guard 3I2 an angular portion 3I4 thereof is secured at 3H5 to the upright I4. The outer end of the guard 3I2 is extended toward the right (Fig. '7) so that a portion 3I8 thereof lies in front of the ends of the shear blades. Beside its guarding function, the guard 3I2 serves as a stop to limit upward movement of the insole (Fig. 2) and thus present the insole in proper relation to the shear blades 49 for cutting off the strip. Also, on the under side of the guard 3I2 is a button 329 for a purpose to be explained. A pin 428 projecting upwardly from the shear blade 292 serves to prevent the free end of the strip S from swinging rearwardly as the applying roll I39 moves toward its operative position.

The strip S is preferably laid, as shown in Fig. 14, from the toe end of the shoe along one side to the breast line and, in order for the strip to extend somewhat beyond the rib at the toe end, a longer end portion is needed on the strip in starting the end, portion than when the second strip S is laid along the other side of the insole from the breast line to the toe (Fig. 15). Consequently, means is provided for insuring a greater extent of the free end of the strip beyond the applying roll when the strip-applying operation is started at the toe than when it is started at the breast line, mechanism for this purpose being best shown in '7 and 8. In Fig. 7 the inoperative position of the applying roll is shown as that which it assumes when the strip is about to be applied to an insole beginning at the toe end; that is, the portion of the strip extending beyond the guide I24 is long enough to extend beyond the toe when the operation is begun at the toe end. This condition is insured by the fact that before the shears were operated the applying roll and strip guide were allowed to move to a higher position when the treadle was released. This position is controlled by a link 322 pivoted to the lever arm I53 and having on its lower end a rearwardly directed pin 324 which engages one or the other of two notches 325, 321 in a tip cam 329 pivoted by a screw 328 to a plate 339. A spring 332 (Fig. 11) is provided between the head of the screw 328 and the tip cam 328 to frictionally hold the tip cam in either of its two positions which are determined by engagement of one or the other of its lower corners with the plate 52 forming part of the machine head. Supposing the machine is oper ated to apply a strip from the toe end of an insole toward the heel end, the link 322 will assume the position shown in Fig. 8 during that operation, the pin 324 being held in a central position by engagement with a slot 333 formed in a plate 338 secured to the front face of the plate 330, the tip cam 323 remaining, of course, in the position' shown in Fig. 7. When the breast line is reached and the treadle released, the link 322 will descend and the pin 323 will engage the shallower notch 32! of the tip cam 323 and tip the cam into the position shown in Fig. 1. Thus, the applying roll and strip guide will not rise as far as before so that when the strip is cut off the free end will be shorter and will be of the right length to start the application of the strip at the breast line of the insole when the strip S is applied to the second side of the insole. When the treadle is released at the end of this operation, the pin of course will engage the deeper notch 323 of the tip cam 325 and the applying roll will rise higher to provide a longer free end on the strip for application to the toe end of the next insole.

When starting the operation at the toe end of the insole as the applying roll is brought into operative position (Fig. 7 the end of the strip engages the guard 3I2 and may not assume its proper position extending over the rib at the toe end. To smooth down this end of the strip and push it into position against the inner face of the rib at the toe so that the toe end of the strip S may be laid over it, the mechanism shown in Figs. '7 and 7 is provided. Piv-oted at 343 to the rear face of the arm I93 is a member 342 having a strip-engaging arm 3%. The member 332 is normally held with its edge face against a stop pin 35.3 by a spring 358. A latch lever 350, also pivoted at 353, has one end pivoted at 352 to a latch 354, the other end of the lever 33!] carrying an adjustable stop screw 356. The latch 354 has a corner 358 adapted to ride along an edge face 333 of the member 3&2, which face is curved from the pivot 333 as a center, the corner 358 being arranged to engage a lug 362 on the member 342. ,The latch 354 is held against the surface 360 of the member 342 by a spring 364 and, as the applying roll moves from the position shown in Fig. 7 toward the position shown in Fig. 7 the stop screw 35% engages the guard 3i 2, causing the corner 358 of the latch 354 to engage the lug 332 and swing the arm 344 in a direction to smooth down the end of the strip S and lay it against the rib of the insole K, as shown in Fig. 7 When this point is reached, a tail 333 on the latch 354 engages a stationary stop 338 secured to the arm I90, causing the corner 358 of the latch lever 354 to be lifted above the lug 362, whereupon the spring 348 acts to return the member 342 to its initial position against the stop pin 343.

In order that there may be cement on the outer face of the toe end of the first strip before the toe end of the second strip is laid over it, the mechanism shown in Figs. 1, 8 and i l is provided. The arm I82 (Fig. 11) whichcarries the inside rib guide I64 has pivoted thereto between lts ends at 310 a lever. having a forward arm 312 and a rear arm 314. The rear arm 314 lies adjacent to the latch I8I (Fig. 11 which latch connects the arm I82 to its operating mechanism. The forward arm 312 of thelever carries a cement-applying nozzle 3'16 (Fig.3) leading from a casing 318 which is supplied with-cement through a tube 380 connected to a suitable tank 382 (Fig. 1) which may conveniently be mounted on the frame 3-2'above the nozzle 313 to provide a gravity feed. Passageyof the cement through the nozzle 316 is controlled by a needle valve having a stern 334 (Fig. 8) surrounded by a. spring 386' which normally holds the needlevalve closed. A trigger 388 is pivoted at 390 to a lug 392 projecting from the casing 318 and has an arm lying beneath a collar 393 on the stem 384- of the needle valve to lift the needle valve when the nozzle 376 and the lower end of the trigger 338 approach each other. The nozzle 376, since it is mounted on the arm 312 pivoted at 310 to the arm supporting the inner rib guide I64, can be moved to the left. The trigger 388, however, is prevented from movement by engagement with a lug 394 on the rib guide I64. Therefore, as the toe end of the insole is being approached in laying the second strip S on the insole, the rib R of the insole K will strike the nozzle 373, moving it leftward relatively to the trigger 338 (Fig. 1) and causing the needle valve to be lifted so that cementwill be deposited from the nozzle on to the already laid toe end portion of the first strip and the applying roll will then carry the toe end of the second strip across the toe end of the first strip, the cement serving to I secure the ends of the two strips together. When this movement of the nozzle 376 occurs, the rear arm 314 engages the latch I8I and pushes it off the arm I82, thus releasing the arm I32 carrying the inside guide I 64 and the nozzle 31S and allowing it to be raised by a tension spring 393 connected between the arm I82 and a stationary bracket 398 on the upright I4. Since the nozzle and inside guide I64 are thus raised out of the way of the insole rib, the applying roll can finish laying the strip up to the rib at the toe end of the insole. When this is done the tr'eadle is released, permitting the applying roll to rise to its highest position, the pin 324 then engaging the deeper notch 325 of the tip cam 326. The insole will now be held against theguard 3I2 (Fig. 2), the flap 238 will be operated by the opera-tors knee to energize the solenoid 2'34, and the shears 202, 204 will advance and cut off the strip substantially flush with the top face of the guard 312, a long free end being thus left on the strip ready to begin operation on the toe end of the next insole. The button 320 on the under side of the guard 3I2 may now be utilized by the operator to tuck the crossed ends of the strips S,

' S snugly into the angle between the rib and the body of the insole at the toe as he removes the finished insole from under the guard 3I 2,

When a strip stiffened with thermoplastic stiffening material is to be employed for reinforcing insoles, the machine is equipped for heating the strip and the applying roll, as illustrated in Figs. 16 and 1'7. In the illustrated construction, a portion of the strip is held in extended condition in a substantially straight line between the guide roll 94 and the guide I24, the guide I01 keeping the strip from sagging. An arm 406 is secured at 43 8 to the frame 92 and to its left-hand end is pivoted at 4!!! a lever to the lower arm 4I2 of which are secured two heating elements '4I 4 which are arranged in tandem but are connected in parallel to receive current through wires 416 from any suitable source. The upper arm of the lever 422 is bifurcated to form a short branch 44'! and a long branch M8 to which is secured one end of a tension spring' l2fl the other end of which is secured to a pin on the arm' 436. Between the branches 4"; MS of the lever M2 is pivoted, on the same axis 4Iil as thelever M2, anarm 42I carrying a stop pin 423 whichis normally held by a spring 425' (Fig. 17) against the short branch 4II. A heating element 422 is connected to the arm I near its lower end. The heating unit is supplied with current through wires 424 and serves to heat by conduction the applying roll I30 and the adjacent parts.

By referring to Fig. 16 it will be seen that as the applying roll I30 is moved toward the operating point about the center of the shaft I06 the portion of the strip which extends in a straight line from the guide I24 to the guide 94 with its mid portion supported by theguide I01 will be brought into a position nearly parallel with the exposed faces of the heating elements 4I4. Just before the applying roll I30 reaches the operat ing point the screw 95 (Fig, 16) comes in contact with the arm 42! and swings the lever 412 on which the heating elements 4| 4 are mounted about its pivot 4I0 into the position shown in Fig. 17 where its position with respect to the skirt is determined by its coming in contact with the guide I01. The exposed faces of the heating elements 4I4 are now parallel to the strip and spaced therefrom a short distance. After this occurs further movement of the applying roll into operative position is permitted since the arm 42! can yield against the spring 425 to permit such movement. Therefore with the applying roll I30 in operative position, the strip, as it moves along, is exposed to intense radiation from the heating elements 4M before it reaches the guide I 24, which also is heated by the element 422, and then passes directly to the heated applying roll I30 which applies it to the insole. In this way the stiffened strip is rendered very limp so that it can be applied to the insole as readily as an unstiffened strip.

It will be noted (Fig. 1'7) that the cement-applying device 3'I8 is omitted but that a feeler 426 occupies the position of the nozzle 315. The feeler is formed on a lever similar to the lever 312, 314 and when the feeler engages the rib of the insole the lever is moved to release the latch IBI, thus allowing the inner rib guard I64 to, be raised above the rib to permit passage of the rib under it.

Either or both of the heating devices M4, 422 may be employed whether or not the strip has been impregnated with thermoplastic material; for example, by using the heating device M4 in connection with laying strip material having a coating of latex cement but not impregnated with stiffening material, it has been found that a very superior bonding of the strip to the insole is obtained.
